Title: Apparatus for the measurement of forces produced within an enclosed space
IPC: G01L7/08
Filed: 1957-05-09
Abstract: 831,288. Electric indicating systems. ASKANIA-WERKE A.G. May 9, 1957 [May 12, 1956], No. 14785/57. Class 40 (1). [Also . in Groups XIX, XXIX and XXXV] Apparatus for the measurement of a force produced in an enclosed space comprises a movable inner member 19 on which the force acts, a movable outer member 25 separate from the member 19, a magnetic coupling 23, 24 and means 28, 29 for applying a compensating force to the outer member 25 to oppose displacement of the inner member 19, and means 30 for measuring the size of the compensating force. As shown, the force produced is due to the pressure differential of fluid flowing past an orifice 18, and acts on a diaphragm 19. The outer member 25 has one arm forming part of an inductive pick-up 26, the current from which is fed through an amplifier 27 to a fixed coil 29 and to a coil 28 mounted on another arm of the member 25. These coils 28, 29 set up a compensating force opposing the force on the diaphragm 19 and tending to restore the member 25 to the position it assumes when there is no force on the diaphragm. The current in the coils 28, 29 is a measure of the compensating force and hence of the force acting on the diaphragm which is a measure of the rate of flow of the fluid. In another embodiment, two magnetic couplings are used, the outer member being in two distinct parts, corresponding to the two arms of the member 25. The principle of operation is similar, the movement of the pick-up 26 being initiated through one coupling and the compensating force applied to the inner member through the other coupling.

Title: Improvements in pack-annealing bed
IPC: C21D9/46
Filed: 1947-06-11
Abstract: 630,521. Rolling. BIRDSBORO STEEL FOUNDRY & MACHINE CO. June 11, 1947, No. 15431. Convention date, Sept. 2, 1941. [Class 83 (iv)] To provide for annealing of flats during transfer from the run out rollers of the rolling-mill to the cooling bed a pack is built up and maintained with the flats in close relation. Subsequent addition of a flat to the rear of the pack causes the front flat to slide down on to the rise and fall transfer bars. Flats 14, Fig. 2, arriving in position on the motor driven live rollers 12 are transferred laterally by pushers 15 and pass singly down a slope 22 to a notch 23<SP>1</SP>. The pushers are carried by crankshaft 16 having an arm 17 for hydraulic actuation at 18. The front edge 32 of a member 26 mounted on a rockshaft 24 then advances the flat up the surface 33<SP>1</SP> to a position where it is held, against falling back, by a projection 601 on an arm 60 projecting over the roller-way and carried by a rockshaft 61 having an arm 66 pivoted to a rod 67 passing freely into a sleeve 70. A spring 65 surrounds the rod and assists gravity in resiliently holding the arm on the flats. Nuts 71 permit adjustment of the spring pressure. The sleeve 70 is carried by a strap 73 pivoted to an arm on a rockshaft 76 by which adjustment to suit different widths of flats may be effected. The front flat may also be restrained at its top edge by arms 78, 78<SP>1</SP>, Fig. 2b, independently pivoted on a pin 81 carried by a lug 82 on the end of the arm 60. The shorter arm is used during initial building up of the pack and the longer during the later stages. The arm not in use is turned back against a stop 84 as shown in full lines at 781 in Fig. 2. According to the degree of slope of the arm 78 this follows the front flat a short distance as it descends the slope 39<SP>1</SP> and ensures that the bottom edge proceeds first. In one form the parts 22, 32 of the bed are integral, but as shown, the part 32 is carried by the rockshaft 24, being supported by a beam 48 linked by connecting rods, adjustable in length at 58 to crank pins 49 on a shaft 55 angularly adjustable in bearings the caps of which serve to clamp the shaft after adjustment. The parts may thus be brought into the position shown in chain lines in Fig. 2, the bed being then suitable for use with sections that do not require pack annealing.

Abstract: 929,512. Knitting-machines. WILDMAN JACQUARD CO. May 1, 1961 [May 6, 1960], No. 15646/61. Class 74 (2). Jaquard mechanism is provided in a cylinder and dial machine in which each jack raising lever 38 is adapted to engage two adjacent jacks 14 and can be operated twice before each knitting station to select both of the corresponding needles 12 in turn. For this purpose one jack of each pair has a butt 15 at a low level and the other jack has a butt 15<SP>1</SP> at a high level. When the lever 38 is operated at the first selection both the jacks 14 are raised whereafter the high level butt jack is immediately lowered by its butt engaging a lowering cam 58 whereas the low level butt jack passes above cam 53. Subsequently the lever 38 may be operated again when the high level butt jack is again raised to cause its butt to engage an upthrow cam 59 at the same time as the low level butt jack is further raised by cam 54. During patterning, gate cam 52, normally raising the needles by engaging their knitting butts, is lowered out of operation so that only the selected needles raised by the jacks elevated by cams 54, 59 are engaged and cleared by clearing cam 51, and subsequently take yarn and knit under stitch cam 45. The selected jacks are meanwhile lowered by cams 55, 60. To enable two selections to be made before each knitting station the jacquard drum 24 is given two movements or the drum is continuously advanced but in either case two rows of perforations are required in the strip 27 to permit the selection of the needles.
